" RlCE-HULLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 300,335, dated June 10, 1884.

Application filed October 26. 1883. (No model.)

To (2% whom it may concern:

Be it known that I, A. M. PATRICK, of Brewton, in the county of Escambia and State of Alabama, have invented a new and useful Improvement in Rice Hulling Machines, which improvement is fully set forth in the following specification and accompanying drawings, in which-' Figure 1 is a front elevation of the machine,

the outer case or jacket being broken away to show the interior construction. Fig. 2 is alike View, partly in section, showing fully the in terior construction. Fig. 3 is a top plan view of Fig. 1, a part of the top broken away to show the internal structure, and one side or section partly detached. Fig. a is a perspective view of part of the frame and easing, the inner drum being removed. v This invention is an improvement in ricehulling machines; and the novelty consists in the construction and combination of the several parts, all as will be hereinafter fully described and claimed.

The general aim in this class of machines is to provide means for hulling or decorticating the grains without cracking them, because the cracked grain is not marketable. By my machine I am able to accomplish the desired ends in a very excellent and most efficient way.

In the accompanying drawings, A, B, and G represent, respectively, the bottom, side, and top pieces of the frame, securely fitted together in any usual way. The fioor and top of the rice-hulling chamber are shown, respectively, at Gr and H, which are made of boards or other suitable material, properly secured to the side posts, 13, of the frame. The floor is close, except in the center, where the shaft N of the internal drum, N, passes through. The foot of this shaft is set in the step E of the floor-piece A, or otherwise suitably fixed, so as to be capable of revolving. Power is communicated to this shaft from any source through the beltpulley P on its lower part. The top H of the rice-balling chamber has the central conical opening, Q, through which the upper end of the shaft N extends. This shaft is set in the piece F on the top piece, 0, of the frame. The conical opening Q allows the rice to be fed into the rice-hulling chamber, falling first on the conical top of N, which projects into opening Q. It is then distributed to all sides. The casing or jacket of this chamber is made up of the staves I, which are preferably secured together in four sections by the sectional bands or ribs K, arranged at the upper and lower parts of the hulling chamber. One section is provided with thumb-catches L at the sides, to work in notches in the posts 13, so that said section can easily be detached for repairs in the interior of the apparatus. The ends I; of each section of ribs or hands are notched, so as to fit snugly against the vertical posts B of the-frame, where they can be secured in any suitable way. (Now shown as being done by nails.) On the inner faces of the stave-sections, and preferably on the middle stavcs, are fixed the pro} ecting spirally-arranged and slightly-flattened beaters S. These are adapted to mesh with the slightly-flattened heaters 1%, arranged spirally on the periphery or outer face of the drum N. These beaters extend, preferably, from the bottom of the chamber nearly to the top of the drum. The drum N is of proper size to allow sufficient space between its periphery and the inner walls of the hulling-ehamber for the proper operation of the machine.

The operation of the machine will be readily understood from the foregoing description. The rice, on being fed into the machine, falls upon the conical top of the inner and revolving drum, and thence passes down and is quickly decorticated by being rubbed between the meshing arms or boaters, and by the time it reaches the floor it will be thoroughly and perfectly hulled without damaging the grain. From the lower part of the chamber it is discharged by means of the spout M.

Having now described my inventiomwhat I consider new, and desire to secure'by Letters Patent, is

1. In a balling-machine, the combination of the following elements, viz: a supportingframe constructed as described, the floor and top piece, G and H, the latter having the feed opening Q, the conicalended drum N, provided with slightly-flattened heaters It, ar-
